Process automation server prioritization

A system comprising one or more processors and memory storing instructions that, in response to execution by the one or more processors, cause the one or more processors to:

• assign a first priority to a first subscriber process that subscribes to one or more input/output (I/O) channels managed by a platform-independent server hosted by a distributed control node (DCN) of a process automation facility, wherein the one or more I/O channels comprise one or more of a sensor or an actuator;
• assign a second priority to a second subscriber process that subscribes to one or more of the I/O channels hosted by the platform-independent server hosted by the DCN, wherein the second priority is lower than the first priority;
• determine that the platform-independent server is experiencing a degradation in performance;
• and
• in response to the determination that the platform-independent server is experiencing a degradation in performance, and based on the first and second priorities, prioritize interaction of the platform-independent server with the first subscriber process over the second subscriber process.

At least one non-transitory computer-readable medium comprising instructions that, in response to execution of the instructions by one or more processors, cause the one or more processors to perform the following operations:

• assign a first priority to a first subscriber process that subscribes to one or more input/output (I/O) channels managed by a platform-independent server hosted by a distributed control node (DCN) of a process automation facility, wherein the one or more I/O channels comprise one or more of a sensor or an actuator;
• assign a second priority to a second subscriber process that subscribes to one or more of the I/O channels hosted by the platform-independent server hosted by the DCN, wherein the second priority is lower than the first priority;
• determine that the platform-independent server is experiencing a degradation in performance;
• and
• in response to the determination that the platform-independent server is experiencing a degradation in performance, based on the first and second priorities, prioritize interaction of the platform- independent server with the first subscriber process over the second subscriber process.
